I used these for the intake hose on a small carburetor. I wanted more narrow, automotive style with the raised teeth but these worked find & look nice. The screw action is smooth on these & they easily fit & clamped tight to my 40mm pipes. The black coating is uniform & did not flake or scratch from tools but the thin edges of the straps look a bit shiny like they may have scaped together in the box.

I am using these to strap angle irons to a vertical pipe to make the pipe wiggle less and I can't drill or weld into the pipe. And these tighten up very much without starting to tear at the slots. Decent for the price for sure.

These are nice clamps, but just to small for my needs. Returns were handled expeditiously.

The product I purchased exceeded my expectations excellent.
